I had the worst flu more than 10 years ago - I can not even describe how sick I was. I had uncontrollable intestinal stuff from both ends, high fever, sore throat, aches, a splitting headache - even my fingers and scalp hurt. I swore my hair even ached. My daughter brought it home from preschool - my mom got it after me. I will never let that happen again if there's any possible way to avoid it.
My husband almost never got a flu shot - and he's a NYPD sergeant dealing with every variety of the general public - they recommend it and make it availabe during work hours - so you'd think he'd get one. But then, about 5 yrs ago, my husband was the only one in the family to get the flu - the kids and I had gotten our shots. He was horribly miserable with it for almost a week. **He has not missed the flu shot since.**
There are many people who have negative ideas about immunizations. They have the luxury to hold those ideas becuase there haven't been epidemics that have ravaged young and old, rich and poor since the miracle of immunizations have been developed. We don't see children dying of influenza or diptheria. We don't see kids crippled with polio - becuase the vast majority of the population gets immunized. Epidemics have become a thing of the past becuse everyone else get immunized.
Part of being guardian is to act in the child's best interest. Her mom is not her guardian due to some action or inaction that reflects either her poor judegement, or inability to make wise decision or inability to properly care for her. IMHO, I think it's your responsibility to override that emotion and do the right thing for your grandchild.
What a blessing you are for being a loving person in your grandchild's life. How wonderful for her to know that there are different layers of people who love her and want the best for her and provide an example of how to live. She is blessed and so are you.
